The BlackBerry Z10 is everything to BlackBerry - and I don't just mean for the platform or the rechristened company that has adopted the brand for which it is most known. The Z10, the first smartphone to run the BlackBerry 10 OS, is a sink or swim device that will likely determine if the company will manage to hold on to its dwindling market share and right the ship that sent it from first to worst in smartphone relevance.

The days of a BlackBerry being the definitive smartphone are gone. The BlackBerry Z10 debuts at a time when smartphones are as much about play as they are productivity, and this phone can thrive in this era only if it can strike a balance between entertainment and enterprise. Can the BlackBerry Z10 be the savior that BlackBerry - the company and operating system - so desperately needs?
